Hello,
I have some trouble with if.
I have three reals, x0, y0 and w0.
If w0 is equal to 0, I would have the vectors P0(x0,y0), else, I would have the point P0(x0,y0).
Thank you very much for yours answers.

Salut Lionel!
Hmm, I think you have to specify your problem.
Saying that there is a "mysterious" if-command which delivers dependent on input a vector or a point .... which answer do you expect. ;-)
So I think for help it's better to post your file.

Maybe you can use "Condition to Show Object" to do what you want?Ok, once again and sorry for the trouble.
I hope that I understand now correct.
In Algebra it does not work (for me), but in CAS (for me) it works.
I deleted my previous post, because the picture in graphic-window doesn't change by changing from "point" to "vector" so I was a little bit confused.
But the logical "proof" confirmed the change.
